Israeli study develops new technique that promises to make solar panels much more efficient
The use of clean energy around the planet is increasing. O Paris Agreement sets targets for reducing carbon emissions, while boosting the development of new technologies in the energy sector. With that in mind, scientists from Israel have made a breakthrough in the solar energy sector by seeking to increase the efficiency of solar panels.
The researcher Avner Rothschild, from Technion's Department of Materials Science and Engineering, together with Ben-Gurion University of the Negev and Helmholtz-Zentrum Berlin, are in an advanced stage of developing this new technology that could drive the growth of solar energy around the world. O study is developing advances in the understanding of how semiconductors work.
Better understand the purpose of the study
Solar panels work with photovoltaic cells or photoelectrochemical cells. Photovoltaic cells do not need external batteries, but semiconductors. Photoelectrochemicals need Batteries external to maintain energy at night.

Semiconductors cause light energy to split water molecules into oxygen and hydrogen and store it in a separate source for later use. However, hematite, the material that is most commonly used in semiconductors, suffers from low efficiency and a consequent waste of energy.
The study developed by the Israelis is testing new techniques to measure the efficiency of hematite and other semiconductors. The hope is that the study will spur the development of solar panels in the future.
''Reducing the use of fossil fuels is the most important challenge facing our planet, and the answer must be to use the free energy that is all around us. Improving solar panels is just another brilliant idea that emerged from Technion scientists.” stated Alan Aziz, CEO of Tecnnion UK.
The use of solar energy is evolving and should continue to gain much more space. Abundant and inexhaustible, the resource is seen as promising because it is cheaper to put into operation than wind energy.
